Aman hiked a distance of 9 miles into the country. he rode back in a car along the same route at the rate of 27 mph. if the entire trip took 3 hours and 20 min, find his rate while walking. mph

Let W be the man's speed while walking through the country
at 27 mph he will take 9/27=1/3 hours = 20 min to ride back the nine miles by car
so he must have hiked for 3h20m - 20m = 3 hours
mph,as the name suggests, is miles divided per hours:
so we have:
W= 9/3=3mph
his walking rate/speed/velocity is 3 miles per hour

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
